redis resource create and expansion

[jhsinger-klotho]

This task is meant to satisfy the redis construct's expansion.

To do so we will:

• Add Create Methods for Each Resource necessary
• Add Configure Method For Each Resource Necessary
• Resources:
  • ElasticacheCluster
  • ElasticacheSubnetgroup
• Add the expand method for an expose construct
• Add the copyEdges logic
• Add EdgeKB data
  • Possible Edges
    • Lambda -> ElasticacheCluster
    • IamPolicy -> ElasticacheCluster
    • ElasticacheSubnetGroup -> ElasticacheCluster

DoD:

• All Methods above are written and have unit tests
• Deploy the ts-redis and verify tests pass
